1. Define a meso compound. 2. Which of the following Newman projections represents meso-2,3-dibromobutane? Please reference the stereorepresentation below to help with selecting your answer. Also assign configuration at the chiral centers. Hint: Carbon 1 is in the front Carbon 2 is in the back. 3. Assign the configuration at each chiral center. How to read the Newman projection: Groups on the right of it are drawn with a wedge to indicate that they are in the front, Groups on the left of it are drawn with dash lines to indicate that they are in the back. Groups at top and bottom of it are drawn with a straight line going up and down. 2. A solution containing \( 0.2 \mathrm{~g} / \mathrm{mL} \) of a pure \( R \) enantiomer in a \( 1 \mathrm{dm} \) polarimeter rotates plane polarized light by \( +3^{\circ} \). What is the specific rotation of the \( R \) isomer? Show calculation.
